Wireless control module

[SRicardi]

Went to start my 2006 truck, it started and then after 2 seconds it would shut off. Tried this 3 or 4 times then locked and unlocked doors with remote and then truck started and ran fine. Checked codes and U0168 came up, saying no communication with wireless control module. Should I replace module or could this be a fluke. Truck has been running fine and has not done this since.
